Resistance

Conductance

Step-by-step explanation:

In any graph the slope represents the ratio of y axis to x axis.

So, in the first case the voltage (V) is on the y axis and current (I) on the x axis. Here the slope is V/I = R. Therefore, slope represents resistance.

In the second case current (I) is on the y axis and voltage (V) is on the x axis. Here the slope formed will be I/V = 1/R = G. Therefore, slope represents conductance.
